Wednesday night was a special occasion for partygoers at The Abbey Food and Bar in West Hollywood. Not only were they relishing in President Barack Obama's surprise announcement in support of gay marriage, but they were also celebrating a surprise visit from pop music's original diva — Ms. Mariah Carey!

Upon her arrival, the DJ sparked a frenzy on the dance floor with an all-Mariah medley, which lasted until about 2 a.m. We're going to assume that DemBabies — 1-year-old twins Moroccan Scott and Monroe — were at home asleep with daddy Nick Cannon.

According to bar-goers, the 42-year-old singer was "very nice and gracious" to her fans, and even posed for a few pictures between shots of Beluga vodka.

Uhm, please excuse us while we go listen to "It's Like That" and cry because we weren't there.
